FS#3474 - 802.11r - Fast transitioning not working for 2nd SSID #8345
Comments
Also running into this on wndr3800's. |
Confirming this bug still exists in the current 22.03.3 stable release. The VLAN is irrevelant. Fast transition only works on the 1st SSID. On a 2nd SSID on the same radio it doesn't. |
Confirming this bug for 23.05.0-rc2 (r23228-cd17d8df2a) on a wax206 also :-( |
Sadly this bug still exists in 23.05.0-rc2, testing on a Belkin RT3200. |
I just tried with 23.05.0 stable release and on the 2nd SSID FT appears to be working but the logs are not as verbose as the main SSID:
I also used Ubuquiti's WiFiman Android app and it was showing the toast roaming indicator switching AP to AP. The WiFiAnalyzer Android app also is showing FT for the 2nd SSID:
Can you all test as well? I did change to the full |
Yes, 23.05.0 fixed this bug for me too (devices are 3 Netgear wax206). Did a walk-around over 3 roaming-zones with both 2.4 Ghz and 5 Ghz WLANs. First and second SSID definitely works now. |

Description:
I have 3 WIFI access points (2x Netgear WNDR4300, 1x Netgear WNDR3700v2) running 19.07.4 r11208-ce6496d796. Each of those APs has a 2.4 and a 5 GHz band. For each of the 2 radios I have defined 2 SSIDs: Home-net and Guest-net.
So each AP has a total of 4 WIFI interfaces:
All the WIFI interfaces of the same SSID are bridged together into a separate VLAN.
802.11r is configured identically on all 4 WIFI interfaces. I'm using a very simple FT config that generates the keys locally based on the pre-shared key and I let most of the required settings to be generated automatically.
Now, my problem is that fast-transitioning works for the Home-net, but not for the Guest-net.
Home-net roaming is really working great and as expected. I can fast-transition between the radio cells of the same AP (2.4GHz <=> 5GHz) as well as fast-transition between the cells of the different APs.
However fast-transitioning of the Guest-net on the other hand is not working at all. Even though it is essentially using the same configuration as the Home-net.
I already tried to provide explicit values for some of the relevant, generated 802.11r settings like NASID and Mobility-Domain, but that does not seem to make any difference.
I also did a test to see what happens, if I delete the 2 working Home-net interfaces. Well, once they are deleted, fast transitioning via the 2 remaining Guest-net interfaces started to work. I could easily roam between the 2.4 and 5 GHz networks of the modified AP.
Given the fact that the previously defunct Guest-net network becomes functional tells me that my network configuration and my 802.11r configuration are not the problem here.
How to reproduce:
//precondition//: a dual band AP with 19.07.04
//result//: fast transitioning is working for the first SSID
//result//: fast transitioning is not working for the second SSID
//expected result//: fast transitioning is working for both/all SSIDs.
